CR1000A router disabling 2.4Ghz wifi band after a few minutes

Since last Friday (2023-02-03), I have been having problems with my Verizon Fios CR1000A router. The 2.4Ghz wifi band just stops working, all the devices get disconnected and the router stops emitting in that frequency. The 5Ghz band keeps working just fine though.

AaFcQw4

Note: in the picture the 2.4 band appears as Disconnected, despite being enabled. However, if a band does not have any devices connected to it, it will also appear as "disconnected" (I tried that by disconnecting everything from the 5Ghz band, and that one also appeared as "disconnected") so it is possible that it says "disconnected" while the radio is enabled, but this is not what it's actually happening for the 2.4 band.

The only way to make the 2.4Ghz work again is by completely restarting the router, but it will only work from a few minutes to a few hours. This is an issue because many IoT devices only work on the 2.4Ghz band. I've had this router for several months, and this never happened before.

Things that I have tried so far:

- Restarting the router. This makes the 2.4 band work for a few minutes or even a few hours.

- Changing the wifi channel (by default it was on auto). Doesn't have any effect.

- Disabling and re-enabling the 2.4 band. Does nothing unless I restart the router.

- Disabling SON (Self-organized network). No effect.

- Reset everything to factory defaults. No effect either.

- Setting different SSID for 2.4 and 5.0Ghz bands. No effect.

I I talked with a Verizon technician and sent me a new router, but the problem reappears immediately, so that rules out a hardware issue.

In the router log, when the disconnection happens, I can see something like this, which seems to be each device connected to that band losing connectivity:

2023 Feb 8 01:26:18 hostapd info [WIFI.6][ADV]Connection Event: BSS=ath1, ACTION=Connectivity, SA=78:67:0e:af:xx:xx, DA=d8:1f:12:38:2exx, STA is disconnected

The wifi spectrum where I live is very saturated, but that hasn't been a problem for over a year. I could understand that some devices lost connectivity or had low speed because of that, but not that the router just disables the 2.4 band and never reconnects again.

I have not made any changes in my network in the last few weeks. No new devices or anything. Maybe there's been a firmware update last week that caused this issue ?

For the moment, as a workaround, I am using a (very) old router I had lying around and set it up as a wireless access point for the 2.4 band, but I'd rather use the wifi from Verizon's router.

I just wanted to know if I'm alone in this or there's more people affected by this issue. Currently I'm out of ideas and if the problem doesn't resolve I'll just buy a third-party router.

Hi Pamela,

Thanks, I already contacted Verizon's customer support, they replaced my router, and even a technician came yesterday to have a look, but we couldn't find the root of the issue.

The only thing I can think of is that the problem might be caused by a recent firmware upgrade. Do you know if it's possible to downgrade to the previous version? I've seen that you offer the current and older firmwares to download at https://www.verizon.com/support/residential/internet/equipment/open-source-software . However, when I try to load one of the firmware files inside the router website (https://192.168.1.1/#/firmware_upgrade), the router tells me that the file is not supported.

Any ideas?

larryjkl

This is happening to me as well. Same exact symptoms. The first tech said to factory reset it but the firmware version was the same before and after so I don't see how that could help ( and it didn't ).

Going to call again; if they can't fix it ( and it happens with a different router ) I'm just going to cancel the service; it's a bit riduclous. I'm using my old wifi router for the moment plugged in to the back of t

I shared some screen shots with the tech; for me, it looks like in one of the log files that the dnsmasq process restarts which seems to knock out the 2.4Ghz frequency.

P.S. Oh, and if I click on the #wifi suggested tag on the right side of this note, it takes me to another screen. Luckily it saves my draft, but really?

wonx

Hi again,

On Friday I spent a while with a level 2 support technician who was very patient and helpful, and we ran a lot of tests, replicating one router configuration at a time. We couldn't find the root cause of the issue, but apparently leaving the router with the default IP (192.168.1.1) did not cause the wifi disconnection, while previously I had it configured to 192.168.1.1.

The thing is, changing the router ip to any other subnet, like 192.168.2.1 doesn't trigger the problem either, it's only when it's set to 192.168.0.1. But why? I still don't know. It had been working fine with that ip for almost a year.

I'll keep you updated if I find out anything else.

magent

Same exact issue. I have spent 15+ hours working on this issue myself, and wasted 5+ hours trying to get the Verizon techs to understand what the issue is. All they want to do is send me new equipment and/or factory reset the router. Both of which has been done numerous times now.

magent

How did you connect your 2.4 access point? Just hardwire it into the CR1000A? Is your CR1000A still broadcasting your 5G? If so, any issues with the 5G from Verizon's box, or with the 2.4 off of your new AP?

Yep, just connect the access point to the Verizon router using an ethernet cable. Make sure the DHCP in the access point is disabled and that they are in the same subnet. And it should work right away.

In my case, I ended up buying a new router on amazon to replace the Verizon box.

magent

So your new router eliminates Verizon’s CR1000A all together? Did you connect your new router to the ONT? What did you do about the MoCA network?

wonx

Yes, I got a Mikrotik Hap AC², that a friend recommended, although the configuration in that brand is not very user friendly.

I left the ONT as is, and just connected the cable from the ont to the "Internet/WAN" port of the new router, and it worked right away. I have fiber at home, so I don't have to deal with coaxial cables.

magent

Has anyone attempted to rollback to the previous firmware? That is assuming it’s possible. I see they are available here:

https://www.verizon.com/support/residential/internet/equipment/open-source-software

airos4

Jumping in, same problem - 2.4 shuts down by itself, although the router status page thinks it's still broadcasting. Power cycling gets me a random amount of time, but within 24 hours it's not broadcasting again.

magent

Has Verizon support been able to help anyone? Each time I call they either just want to factory reset the router or send me a replacement. The other things they suggest have already been done (disable SON and put 2.4 radio into compatibility mode).

I call every couple of days to see if they have any other suggestions. But it’s getting exhausting spending an hour trying to explain to yet another technician what the issue is, and go through the whole history.

I have another access point on hand that I can use to get around this issue, but on principle I want my Verizon service to work the way it is meant to, without disconnecting half of my devices every couple of hours.

aPastafarian

Just wanted to add to the pile. I have the same issue, 2.4 seems to stop receiving/ turn off and for me, it appears to happen about once a day. Really frustrating as it requires a reboot to temp fix it. I haven't contacted support yet, but will tomorrow. I have strong doubts they will be of any useful assistance, but they can't be any worse than Hulu's 100% useless support. Since I have a few old routers around, my strategy is to set one up as an access point to band-aid the issue till Verizon figures it out. My completely uneducated guess from reading here is it's probably a firmware issue.

The chat support didn't really help me much, they kinda went in circles, enabling and disabling SON and resetting the router. They finally gave me a phone number to call (can't post it here unfortunately, or it gets deleted), and from there I spoke with someone who passed me to a lvl 2 technician. I spent more than an hour on the phone with him, but he seemed very knowledgeable and willing to help, and ran lots of tests to try to isolate the issue. At the end he didn't find the root cause, but he 100% tried and didn't waste my time.

aPastafarian

I spoke with support this morning. The rep was fine if no help because a support call isn't fixing this issue. He didn't have inside info but said this will be fixed in the next update. My intention was to be a squeaky wheel, so mission accomplished? If the issue remains in a week or so, I will call and ask for a credit, not because the small discount will amount to much, but to increase the volume of my squeak.

magent

I called again yesterday for maybe a ninth time. Not surprisingly, they did not have any updates. After having me do a factory reset of the router for perhaps the sixth time, they said this issue must be related to something on my network. While all of the technicians are polite and as helpful as they can be, none of them seem to want to acknowledge the issue perhaps could be with the router. They claim I am the only customer with this issue.

aPastafarian

Well, I went 30hrs after contacting support before the issue reappeared, then I rebooted and it happened again within 5 minutes. I set up my 'old' Asus router as an access point to take over the 2.4ghz roll. I hope someone posts here when the router firmware is fixed so I know when it's safe to disconnect the Asus.

Sparks123

Same problem here. For me the problem began circa March 7 (today is March 11, 2023). Firmware version is 3.2.0.7.

To temporarily bring back the 2.4GHz band, you can change one of the settings for that band and apply changes. I find that a bit easier and faster than unplugging the router.

It might help technicians understand the problem better by telling them that WiFi analyzers (e.g., WiFiMan by Ubiquiti, on a cell phone) show no 2.4 GHz radio on the CR1000A is transmitting. This shows that it is not just the Guest and IOT SSIDs that went out. (Those are 2.4 GHz only, so of course they are not listed as available networks when the 2.4 GHz band is out.)

Chrisl2022

Adding on to this... Same issue with 2.4 GHz disappearing. Firmware 3.2.07 on CR1000A. Hardware version 0.0.7.

Chris

Jack-C

First occurrence 3/11/2023, occurring daily since. 3/17/2023 twice today so far.

magent

Has Verizon given any of you any additional guidance or support with this issue? Or even acknowledged that it is a common problem? All they continue to do for me is factory resets and replace the router.

conazo

I'm having the sames issues with CR1000A dropping 2.4Ghz at least twice a day this is very frustrating since we are paying for a service that's not working properly. VERIZON PLEASE THIS ISSUE ASAP!!! MY KIDS ARE DRIVING ME CRAZY COMPLAINING ABOUT NOT HAVING INTERNET ON THEIR TABLETS AND TVS!!!

jradwan

I've had the same issue for about a month, maybe longer. Entire 2.4 GHz shuts down, all smart devices disconnect and will not reconnect unless router is rebooted. Same version as others in the comments, CR1000A running firmware 3.2.0.7 and hardware 0.0.7.

According the open source portal https://www.verizon.com/support/residential/internet/equipment/open-source-software the latest firmware update for CR1000A (3.2.0.7) happened on Feb 3, 2023. The next most recent release is from May 17, 2022 (firmware 3.1.0.21). No idea what to do with the file once I download the zip-- I can't find where to go in the router settings.

There's this page in the router to upgrade the firmware: https://192.168.0.1/#/firmware_upgrade

I only tried installing a previous version of the firmware, but it didn't let me.

aPastafarian

I've kind of given up on this for the mean time. For both cr1000's I've used the problem's interval increases over time till it's many times a day. Replacing and resetting the router doesn't accomplish anything and I'm not entirely sure it's a firmware issue or a hardware fault. It could well be that the reason many of us have received replacement routers only to have the same issue is that the replacement is already a return that checked out because this fault doesn't occur right away. I am fortunate to have an oldish Asus router that I can use as a 2.4ghz access point, it certainly uses more power than just one router, but it works . When I set up the access point, it took about 5min after restarting everything till 2.4ghz shut down on the Verizon router and moved to the Asus. I hope this issue gets resolved and I can go back to just one device but I've already spent hours trying to resolve it and the next step would be to threaten to go back to Optimum, which I really don't want to do right now. This whole thing certainly will make it easier to jump ship eventually....

soramorgan

Same issue we're experiencing. CR1000A on 3.2.0.7 firmware/ 0.0.7 hardware. SON disabled. 5GHz stays available, but 2.4 will go down intermittently.

Have tried factory resetting and different band channels with no success. I've considered trying IoT, but 99% of our devices that use 2.4 are smart devices anyways so I rather not be bothered.

I'll most likely try using an older router (TP-Link AC1900) for a couple days or few weeks to see if we're good.

Chrisl2022

Looks like they updated to firmware 3.2.0.8 over the past week or so. Has the issue been resolved for anyone?

Chris

aPastafarian

Still 3.2.0.7 here....

magent

Same here. 3.2.0.7

Chrisl2022

Give your routers a reboot to see if they have the new firmware load on boot up.

top83banana

Make sure your IoT Network has a same Wi-Fi name as your Primary Network.

Chrisl2022

I switched back to using the 2.4 GHz wireless last night and the 2.4 GHz radio disappeared again this morning. The new firmware did not resolve the issue . I am back to using my separate access points for 2.4.

Chrisl2022

Here's what I have done and it is working okay for over 4 days now:

I don't use the SON (self organizing network) feature.

Renamed the regular 2.4GHz network name to something else so no one connects to it.

Used the IOT network and renamed it to what I usually use for my 2.4GHz Network with the same passcode.

Devices have been connecting through the IOT network for over 4 days and the radio has not failed yet.

I'll just leave like this until we hear news of this issue being fixed permanently.

Chris

aPastafarian

I really hope this works for you but I have tried everything you have and it hasn't worked for me. The radio failure is inconsistent for me, I can go 4-5 days up, then have it go down every hour or less . I also don't know how Verizon is working the new firmware rollout, it's been over 3 week since I saw the first report of 3.2.0.8, I'm still on 3.2.0.7. There can't be that many out there for this slow a roll out? I'm thinking about forcing another swap, if just to annoy them . In pretty sure it won't help one bit and that this router is little more than e-waste.

nycuser2

Have people solved this by getting their own router? I think that's the only option at this point apart from switching to another provider. I just got a new router, separated the networks by band, only connected Nest and smart devices to IoT network, and the issue is happening even more frequently. Been having this issue for months as well.

Tysons22182

New home. New network. Went with Verizon instead of Xfinity. The Verizon CR1000A router continuously drops the 2.4ghz (and connectivity for the devices on 2.4ghz) connection requiring several reboots per day.

I tried turning off the Self Organizing Network feature which actually seemed to fix the problem for four days. But today, the router is back to dropping the 2.4 channel over and over, reboot after reboot.

Anyone from Verizon on here? Please help!!

aPastafarian

I wish I could give you some hope, but I ended up buying a replacement router after 2 swaps (3 total) cr1000a's) that all had the same 2.4Ghz issues. Good luck!

nycuser2

I also ended up getting a new router, eero pro. Tried 2 different Verizon routers (same model though) and no dice. Really sad.

Chitchat7295

Since replacing my CR1000A with the CR1000B (HW ver 103, running Firmware 3.1.1.18), I've now gone 11 day(s) 12 hours 10 minutes 36 seconds without the issue showing up! I'm not saying it's solved by this combination of Hardware & Firmware just yet, but...

Has anyone in this thread had the issue with the configuration I have here?

For those who want to try getting this hardware, you should:

Call your local Verizon store to see if they have the CR1000B in stock.
If they do, call Verizon support and go through the 101 troubleshooting with the tech.
Once they agree that it may be hardware related, you can ask them to allow you to swap out the unit at your local store. Or - as I did - ask the agent to send out a technician with a note that they need to bring out the CR1000B HW and hope that one of the units in their truck is the CR1000B.

jay061

is your router still holding the 2.4 signal

Chitchat7295

29 days in and NO 2.4Ghz radio issues! So, I think it's safe to say the #cr1000b hardward solves the #wifi issue.

Note: The agent(s) I spoke with had no ability to ensure a CR1000B was going to ship, though they made a note on my account.

Steps I recommend:

1. Call your local Verizon store and see if they specifically have the CR1000B (hw rev 103) in stock. If they do, you can tell the agent you'd like to swap for a router from your local store.

2. If your local store doesn't have it in stock (as was my case), the agent dispatched a technician to "troubleshoot" the issues. When the tech arrived, I explained the situation and he luckily found a CR1000B in his truck.

3. Have the agent make a request to only ship a CR1000B and hope they do. If they send a CR1000A, just call back and ask them to swap it out again.

Best of luck to others dealing with this

acrane76

Anyone have a solution to this? Seems like it's having more frequently lately. I'm on the 3.2.0.8 firmware version. I've called Verizon, and they didn't mention they were aware of the issue. He didn't go into any details or timelines on when it would be fixed. All my IOT devices go down and it's becoming frustrating to say the least.

NJ_Biker_Dude

After working for the past several weeks trying to troubleshoot this same problem, I reached out to Verizon this morning to request a replacement of my CR1000A with a CR1000B. I explained about all the research I had done (specifically referencing this thread), and they agreed to have a technician come to my house to swap the router. They had an appointment available for this afternoon (SAME DAY!), and the tech ended up calling me to say he could come by early (my lucky day!!!).

He stopped by the garage to pick up a CR1000B since he didn't already have one in his truck, and was at my house about 30 minutes later. He swapped the router without any questions, and everything is currently working. Of course, it has only been a few hours, so only time will tell if the issue is actually resolved. The tech said that he had never heard of this issue, so I directed him to this thread so he could learn about it. He said he was going to follow-up with a more senior tech that he works with.

FINGERS CROSSED!!!!

Thanks to everyone for sharing their experience, and especially @Chitchat7295
for posting this solution!

NJ_Biker_Dude

I made it 8 days without any issues, but yesterday my CR1000B started exhibiting the same issue. The 2.4Ghz wifi network just seems to disappear. Now it is happening quite quickly after a router reboot.

I called Verizon and they said they are seeing some alarms on my ONT so they want to send a technician out to investigate. I'm not sure how alarms on my ONT could be related to the 2.4Ghz wifi network not working, but I'm happy to have them investigate.

I am so ready to be done with this issue!!!!!

Virulane

I have the CR1000B since April, same issue dropping 2.4 g daily now...

EVERONE with this issue needs to call Verizon Router Advanced Support (direct number) 929-438-6464.

Tech support acknowledges this is very likely a firmware issue and agent I most recently spoke to said he has escalated it a few times for other customers but it usually doesn't go anywhere. He advised me to call the above number and said to tell anyone else with this issue to do the same.

Normal Fios tech support doesn't have many options at their disposal to deal with this type of issue involving routers. Check ONT, reboot router, ch. scan, reset, send replacement is about all they can do.

Advance Router support (India) indicated that they don't have any/many other reports about this. (how true that is I don't know)

Essentially not enough people have complained DIRECTLY to them to put it on their radar.

Nothing will get done unless we all complain.

When you do call the number above, explain that it's widespread and likely firmware issue, to avoid having to go through the basic troubleshooting steps, rebooting, resetting changing Ch's ect... that we have all done countless time before, along with everything else we've done that doesn't fix the issue. SON, IVP6, Security settings, etc... etc....

acrane76

So I did a factory reset today, and I received a new firmware version ("3.2.0.11"). I don't know if it fixes the issue, but it at least updated.

ci1025

I gave in and did a factory reset. It did in fact update me to 3.2.0.11 (I had been stuck on 3.2.0.8 with no OTA updates)

Fingers crossed this fixes the issue.

ci1025

Update: Issue persists on the 3.2.0.11 firmware after a factory reset.

I spoke with Verizon and they are replacing the router. Based on this thread, I am not optimistic it wont happen with the new equipment, but i will give it a try.

ci1025

Update: Swapped with a new router and set up from scratch. And to no one's suprise, the issue occurred less than 15 minutes later. I have already passed along the feedback to the support team and have just written a message to the Verizon leadership team via the online form. In the meantime, looks like i am switching back to the previous gen router.

acrane76

Update: The firmware (3.2.0.11) installed a week ago, and so far I haven't had any issues with the 2.4 ghz channel dropping. I'm hopeful it's a permanent fix, but still skeptical.

ci1025

For what it's worth, 3.2.0.11 didn't fix it for me, even after doing a full factory reset. The new CR1000A sent to me by Verizon also updated to 3.2.0.11 upon the initial setup, and the 2.4Ghz dropped about 15 minutes later.

I tried turning off automatic channel selection for 2.4Ghz and disabling DFS channels, but i still only made it 3-4 days until it dropped again.

jay061

after reading 9 pages of posts about this and having the same issue myself, it's obvious this routers problem will not be fixed and Verizon doesn't seem to care... what a disaster, everyone that bought one these from Verizon needs there money back, this is completely unacceptable

ci1025

I gave up and switched back to my G3100 and its already been up for 7 days straight with no issue. I'll stick with this until Verizon gets their act together and fixes the CR1000A.

acrane76

I've had success so far with the firmware update. It's been up for 15 days and no issues with the 2.4ghz channel dropping.

Interesting. That's great. I tried firmware 3.2.0.11 on 2 CR1000A routers (both factory reset) and couldn't make it further than 3 or 4 days max without the 2.4Ghz band dropping.

NJ_Biker_Dude

My 2.4GHz network continues to be relatively stable with the G3100 (only 1 brief dropout that I am aware of).

I did just send a message to Joe Russo (Verizon's Executive Vice President & President of Global Networks and Technology), advising him of the situation we are all dealing with. I used the webpage that someone else suggested: https://www.verizon.com/about/our-company/leader/contact/925485

I am eager to see what type of response I get.

I sent a message that same way too. No response yet sadly, but hopefully it helps

NewUser23

You're not alone. This is very frustrating and VZ doesn't inform anything to new users.

acrane76

I thought the new firmware (3.2.0.11) fixed my issue as it was stable for several weeks. I'm now back to every day having to reboot the router because 2.4 GHZ is disconnected. I wish I kept my old Verizon router that had no issues at all except the range wasn't that great.

ci1025

I noticed my G3100 was updated last night to firmware 3.2.0.12.

Does anyone know if the CR1000A got this update as well? It's probably wishful thinking, but i'm wondering if it fixes the 2.4Ghz issue. I am hoping to switch back to that model when/if Verizon gets their act together.

mosskein

It really looks like disabling DFS fixes the issue. I disabled my one about a week ago and haven't faced any problems so far. To disable it, open the Fios app on your phone, then choose the Internet, scroll to the bottom, and go to Advanced Settings. DFS Channels will be the first setting there.

I updated my service/router about 4 months ago and had the same issue. I had spent a lot of time with support with no luck. Verizon had already replaced the router once but it did not help. My 2.4 Ghz disconnects every 2 weeks or so and the only way to bring it back is by rebooting the router. I have router CR1000A, firmware 3.2.0.11. I regret now upgrading and I hope they find a solution.

Same exact issue - got the router a couple months ago, worked fine till yesterday, and now cannot maintain the 2.4 ghz band. Rebooting fixes it for a few hours, etc.

I’ll phone in my complaint so it’s on record.

I’m especially irritated because I never wanted a new router to begin with, and told them so. But when I changed service this summer, they automatically sent me this fabulous piece of hardware and required me to return the old one. I should have refused delivery.

I called Verizon yesterday which would probably be the 4th or 5th time I've called on this issue. Each time, support has mentioned that they don't have any knowledge of this issue. I told him to go find this thread as there are so many users experiencing this 2.4ghz channel issue. I opted to swap the router for a new one. I picked it up yesterday which came in a sealed box so it was definitely new. I also notice that the Verizon branded sticker was white and on the center of the unit. I was hopeful that this might be a newer version and that the issue would be resolved. Unfortunately, today the 2.4ghz channel disconnected and had to reboot to get it working again. I didn't even have the new router for 24 hours. TDLR: Issue still not resolved after swapping for a new CR1000A router w/ firmware 3.2.0.11.

After multiple calls to tech support, each which resulted in an open and closed case with no actual resolution, i tried to send another message to executive relations using the link in a previous post. They contacted me quickly to gather more info, and let me know they would reach out to their internal network team for a resolution. Today they let me know that their engineers are aware of this 'known issue', are actively working on a resolution, and will contact me with any updates. Fingers crossed they will actually fix this once and for all

I was working with Sebina with executive relations since June, I had informed her of this thread as well as some of the many non Verizon forum threads regarding this issue. She got engineering involved.

After multiple updates as of this week the engineers still could not see anything wrong or any issue. Even after looking at my logs at the time I was having the issues. Their final recommendation was to downgrade to the older router or buy my own.

Essentially they dragged it out 3 months to tell me the same thing NY tech support originally recommended.

Good luck in your attempts, but at this point I have no faith that Verizon is willing or capable of ever getting this resolved.

I don’t know if the 2.4 ghz is showing because of a reboot or because this is a fix. I logged on to the app on my phone went to Advance settings and DISABLED DFS channels. It mentions minimizing available channels and limits 5 ghz and allow more acces to 2.4 ghz. I guess we’ll see in the morning.

Nope...

No combination of DFS, CH's, width, Enabling/Disabling 5g, 6g, guest, QOS, WWM, WPS, SON, IPv6, UPnP, Firewall, etc... has any effect.

We've all had multiple tickets, replacement routers, multiple factory resets, most have had tech visits.

Changing some settings causes a router reboot, or 2.4g disable/enable which only temporarily fixes the issue. Almost as if something is causing the 2.4g antenna/chip to be overloaded and freeze up. It's not due to frequency interference.

The engineers really need to dig deep. One of the first things I would do is determine if we all have something in common on our networks or otherwise that could possibly be causing this. Why are so many people experiencing this issue but seemingly not everyone? What do we all have in common?

From there they can try to figure out why it effects only the CR1000 series of routers and not customer owned routers.

Happened to me as well.

I installed Verizon FIOS in March, it used to work pretty well until now, recently this October I realized all my 2.4GHz devices are gone from the network. Restarting routers helps for some time. I noticed in "Advanced / Diagnostic & Monitoring / System-wide connections / 2.4 GHz Wi-Fi Access Point" the connection status is "Disabled" for some reason at that moment, while the primary 2.4 GHz wi-fi network was enabled in the "Wi-Fi" section.

I think I know the correlation. My son has installed old dusty PS4 recently and started downloading games using Wi-Fi.

PS4 supports only 2.4 GHz so I'm pretty sure 2.4 GHz modem in CR1000A is overheating and goes offline. So maybe try to find out which device is the biggest 2.4 GHz traffic consumer and maybe try to switch it to 5 or 6 GHz

I'll give it one more chance and if it happens again will switch to my old good TP-Link

Model Name: CR1000A

Firmware Version: 3.2.0.11

Verizon executive relations just got back to me with an update:

Please be advised that our Network team is aware of the ongoing router issues, and have advised that when the manufacture sends out the next firmware update it should fix it the current issues our customers are experiencing. We currently do not have the release date for the next update.

OrangeFox333

Not sure if it matters at this point but we have been having this problem as well for the last couple months. Fingers crossed on the firmware update and thank for all the previous posters hours spent dealing with this!

Just heard back from Executive Relations.

IT IS OFFICIAL, there will be NO fix for this issue effecting the CR1000 series of routers!!!!

The reason why this issue was not made a priority or taken seriously was directly due to the lack of concurrent open engineering tickets. Tickets of this nature are linked to the MAC address of the router. When a customer replaces or swaps their router downgrades to a different model, switches to their own router, makes any changes their service, or a technician visits your house the ticket is automatically canceled out in the system.

All the complaints using the executive contact form did generate some attention.

Verizon corporate executives and both manufactures are now aware of the issue we are all experiencing.

Verizon's Product Development Team has confirmed that the CR1000 that was first released on 7/19/2022 will be phased out beginning in the 2nd quarter of 2024. They cannot provide any information as to what it will be replaced with as there has been no official product released to date.

The only firmware updates for the CR1000 series of routers going forward will be of security in nature.

Verizon will not be compensating anyone.

The ONLY option going forward (aside from legal & governmental) is to downgrade to the G series router, purchase own router, or wait it out.

It doesn't

I've been on The new firmware and issue is still present, occurring even more frequently for me now

B3njamminnn

Yeah, I've been on the new firmware and the issue is now even worse for me
